Abstract:

An asynchronous explosive logic safing device which is mappable as a network on a single surface to perform the safearming function for an explosive device or warhead. The safing device uses explosive logic AND gates and ANDOR gates in conjunction with a complex logic gate to form an asynchronous network that absorbs the variation in detonator input signals and only propagates the detonation signal to the warhead when a given number of a set of detonators initiate.
